The two output signals enable the connected microcontroller not only to count how often the knob has been turned, but also to determine the direction of rotation. The integrated push button additionally signals when the knob is pressed.\u003c\/p\u003e \u003cp\u003eThe gold-plated contacts ensure reliable connections and reduce contact resistance. The principle is based on two offset sliding contacts that generate pulses alternately, while a third connection provides the common reference point. This produces a code from which the software determines the direction of rotation.\u003c\/p\u003e \u003cp\u003eApplications include rotary knobs for menu navigation on displays, volume controls in audio devices, encoders for detecting the position of motor shafts, and parameter inputs on measuring devices. In a weather station, for example, the encoder could switch the current temperature display between several sensors.\u003c\/p\u003e \u003cp\u003eConnection is made via pin headers to the digital inputs of a microcontroller board; the pulse sequence is evaluated in software. Debouncing in the firmware prevents errors caused by contact bounce. The module does not require an external power supply; the signals run through the controller's input pins.\u003c\/p\u003e \u003ch3\u003eSafety Information\u003c\/h3\u003e \u003cp\u003eThe module is intended exclusively for building prototypes and for testing and development purposes and is not suitable for electrical installations in the household mains network.
